Application filed June a, 1912. Serial No. 701,223.

To all whom it may concern Be it known that 1, PETER E. KROEHLER,

a citizen of the United-States, and a resident of the city of Naperville, in the county of Dupage and State of'Illinois, have invented.

certain new and. useful Improvements in Spring Constructions for Upholstered Dav? enports, Couches, and Chairs; and I do here-' by declare that the following is a full, clear,

and exact de cription of the same, reference.

being had to the accompanying drawings, and to thenumbers of reference marked thereon, which form a part of this spec fication.

Upholstered davenports, couches and.

chairs have usually, heretofore, been constructed' either of a metal fabric secured practically at the top of the bottom frame,

' or have been constructed with comparatively deep spiral- (or other) springs, the lower 1 ends of which are supported usually upon top of the frame.

webbing or slats fastened at the bottom of theside and end fr me members. Inthe former construction insufficient resiliency re sults; in the latter, insufiicient durability, v and the occupation by the springs of practically the entire space Within the bottom frame has been deemed necessary.

The object of this invention is to alford a construction wherein the desired resiliency may be obtained and also great strength and ,durability, and in vwhich the spring conthe top of the. frame, and occupying but slight space in the spring or. upholstered. frame, thereby'adapting the construction to beused for couches, vdavenports and the like,

Where room for storage beneath the spring structure'is frequently an important object.

The invention (in a preferred form) is shown in the drawings, and hereinafter more fully described.

- In the drawings: plan view, broken away, of a device embodying my invention. Fig. 2 is an enlarged, fragmentary, transverse section thereof.

' Fig. 3 is a similar view, slightly modified,

of the invention to afford Figure 1 isa bottom As shown in the -drawingsi 1, indicates the side frame members, and 2, the end frame members of the couch or davenport seat, which, as shown, is constructed of wood of suitable width and thickness, but, of course,

maybe constructed of any suitable material.

An angle bar sprlng'frame is secured within said main frame, comprlsing lntegrally connected side and end members engaged in place within said frame by means of screws,

bolts or otherwise, engaging through the I downwardly turned flange thereof, andthe inwardly'projecting web of said angle bar frame, is provided with apertures arranged suitable distances apart at opposite sides and opposite endsof the frame. Engaged in each of said apertures in. said side-and end frame members 3 and 4, are strong,

coiled springs 5, which are connected in pairs transversely and longitudinally of the frame under tension byv means of transverse wires 6, and longitudinal wires 7, respectively, as shownin Fig. 1., Threaded and y seated upon the wires 6 and 7, at their intersections, are short, downwardly diminishing spiral bed or upholstery springs,the lower ends of which are engaged in unvarying relation relatively to each other on said wires. i

Secured to the side and end members 1 and 2, of the main frame, and around thetop thereof, is a strong canvas covering 9, as shown 1n Figs. 2 and 3, which 13 drawn with sufficient tension over the upper or larger ends of. the upholstery spring to exert considerable stress thereon, and also on the springs 5. The padding or upholstery 10, and covering fabric 11, are placed thereon in any suitable manner, and engaged around the margins of the main frameby suitable upholstery able means. I

Inthe constructionillustrated'in Fig. 3, instead of an angle bar interior frame, a bracing StIfilP- 14, of 'woodor other suitable material a ording an inner frame, may be provided around the top of the main frame to strengthen and reinforce the same against the draft of the springs thereon.

The operation is obvious from the construction described. Downward pressure applied on the upholstery or cushion, serves to depress the coiled bed or' upholstery spring, and the stresses applied thereon are directed, by means of the transverse and longitudinal wires 6 and 7 ,transtacks 12, orother suitids I granted onthis application,

Ni V

ersely and longitudinally the frame to the coiled pulling springs 5, Where such stresses are absorbed, thus anording an exceedingly.

soft and resilient construction, in exceedlngly small compass as to thickness.

When used as the cover for a box couch,

a davenport' or otherwise Wherein it may be desired to store bedding Within or partly to avoid engaging in such fabrics as may be stored there1n,;as shown in Figs. 2 and 3,

or closed -inwardly Within the spring, to preventv engaging. and tearing such fabric.

It. is tobe understood, of course, that I: have shown but one embodiment of my in vention; although numerous modifications and variations in detail are I possible.- I therefore do not purpose limiting the patent v otherwise than necessitated by the prior art.

I claim as'my' inventions 11A device of the class described embracing a main frame," an a'ngle bar frame securedtherein and extending around the top thereof With the Web turned inwardly and having apertures therein, transverse and longitudinal flexible irallel members ar crossing:points of said members acting to "bind the same together to be supported a ewe-nee,

, ranged within said frame and below the same, downwardly directed pulling EPL'lH connect ng said members at their ends \\1 h sa d Webs at said apertures andumler tension,' upholstery springs mounted at the thereon,-and upholstery engaged around the margins of-the main franc and drawn over said upholstery-springs to tension the same and the first described springs.

2. A device of the class dcscril d enibracinga inain'fran'ie, an angle bar lraine secured therein and extending around the same with the Web turned inwardly, -trans verse and longitudinal unconnected parallel supporting Wires arranged within said frame pulling springs connecting" said wires at their ends with said webs and under tension and upholstery springs mounted at the crossing points of said Wires acting to bind the same together and-supported there 1l.

I in testimony whereoi I l are hereunto sub scribed by name in'the presence of two subscribing itnesses.

KROEHLER.
